IPC: G01C13/00
Filed: 1931-06-05
Abstract: 370,253. Indicating liquid levels. COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL, 79, Boulevard Houssmann, Paris. June 5, 1931, No. 16490. Convention date, June 12, 1930. [Class 123 (i).] Apparatus for sounding depth of water comprises a flexible tube U rolled upon a reel and weighted at the end which extends into the water. The other end is provided with a joint with the tube T which remains fluidtight during unrolling of the tube U, and the tube T is connected to a compressed air chamber C through an expansion chamber D and valve V. An electric conductor F which may be embedded in the wall of the tube U or secured to the outside, extends into a small chamber D<1> at the end of the tube U, and an electric circuit is completed through the water or through a second conductor whereby a relay r and electromagnet A are energized to open the valve V until water is expelled from the chamber D<1>, when the circuit is broken. The pressure gauge m then indicates the depth of the submerged end of the tube. The reservoir C may be supplied by an air compressor which is controlled by the pressure in C.

Title: Improved Method of and Means for Braking Explosion Motors.
Inventor: WADE HAROLD
IPC: F01L13/06
Filed: 1916-11-18
Abstract: 112,644. Wade, H., (Saurer, A., [Firm of]). Nov. 18, 1916. Stopping.-In means for braking or stopping four-stroke internal-combustion engines, the camshaft is advanced through an angle of 90 degrees or less in order to produce compression effects in the cylinder and suction piping. The cam-shaft 3 carrying the admission cam 11 and exhaust cam 22 carries a screw 7 and is driven by a screwed toothed wheel 4. Longitudinal adjustment of the shaft by means of a lever 8 produces rotation of the shaft up to a maximum of 90 degrees. The action of the valves may thus be advanced up to a complete stroke of the piston. The suction piping is shut off and compression effects dependent upon the extent of the cam-shaft advance are produced. At one point in the operation, the admission valves open automatically to admit from the suction piping air which has been compressed during a previous cycle. To prevent noise due to this action, an auxiliary cam 12 is provided to produce the same effect.

Wick burners, annular; wick-operating and wick - locking devices. - The wick - adjusting mechanism of burners, particularly of the "giant" class, of the type having inner and outer wick tubes connected together to form an annular wick space and an oil reservoir, includes a vertically movable element or rod 20, Figs. 1 and 8, arranged within a lateral offset portion of one of the wick tubes and guided at longitudinally spaced points to restrict it to a movement substantially parallel to that of the wick. In the construction shown, the inner wick tube is formed with an inwardly extending offset portion. The wick elevator 22 has yoke and stiffener portions 22<a>, 22<b>, terminating in angle parts 24, and is secured to a central reduced portion 21 of the rod 20 which is guided at its upper end by a sleeve 15 and at its lower end by a tube 17 provided at the top and bottom respectively of the offset portion of the inner wick tube. A rack member 35 having arms 39 and a keyhole slot 40 embracing a neck portion 20<b> of the rod is operated through the medium of a pinion 45, spindle 46 and hand wheel 50, the spindle being journaled in bearing apertures in opposed branches 47, 48 of a bracket 49. A pair of resilient wick grips 55 are secured to the extensions 24 of the elevator, their upper ends being provided with inwardly flanged lips 57 for engagement with the upper edge of a wick carrier which is adapted to rest upon horizontal flanges 26 of the elevator. When the elevator is raised to its highest position the upper ends of the grips, released from contact with the outer wick tube spread outwardly and enable a wick and carrier to be removed. A shield 65 conceals parts of the wick stop mechanism D extending below the burner tubes and is secured to the branch 48 of the spindle bracket by the engagement therewith of lips 70, the notch 68 providing clearance for the spindle.

Abstract: 169,421. Neeper, W. M. June 22, 1920. Sunken ships, raising; diving- chambers. - A diving-chamber 1 suspended from a salvage ship and having means for propulsion is provided with a grappling-device held thereon by an electromagnet and suspended from a floating pontoon. The chamber 1 is formed with double walls 2, 3, Figs. 3 and 4, ovate in cross-section, in contact at the ends and separated at the sides by ribs 4 forming spaces 9. A ceiling 5 with a, dome 7 is provided. between which and the outer shell are radial ribs 6. Below the floor 8 is a ballast compartment 10, with radial ribs 11, pierced at 33, and a central chamber 12, with water-tight covers 13, 14, which may be used as an air-lock in entering a sunken ship. The device is lowered by cables 19, Fig. 1, and flexible conduits 21 are provided for compressed and fresh air, electric cables, telephone lines, &c. The compressed air is led direct to the space 9. Propellers, driven by motors 24, 25, and a rudder 27 protected by a grating 28, together with an anchor 31 on a cable wound on a windlass 29, enable the chamber to be manoeuvred. The ballast compartment 10 may be flooded by means of a valve 32, Fig. 3, and emptied by the admission of compressed air through the pipe 34. At the forward end of the device are an electromagnet 36 and stay members 37, 38 adapted to engage the beam 39, Fig. 2, which is provided with an armature 40 and carries at its lower end a hook 43 adjustable by means of bolts 45. The chamber 1 is lowered with the beam 39 in position till the hook 43 is level with the keel of the wreck, and then moved forwards and backwards till the hook catches under the keel. A compressed-air nozzle 60, Fig. 2, is used in this operation to clear away silt &c. The chain 42, Fig. 1, by which the beam is independently suspended, is then tightened, and the beam released by de-energizing the magnet. A hook 48, with a part 49 having crossed slits 50, 51, Fig. 19, through which pass the links of the chain 42, is lowered till it engages the gunwale, and, when tension is applied to the chain to raise the ship, binds on the chain. Fig. 25 shows a method of passing a chain 102 under a ship 103 by means of a grapple 95 bolted to the stays 37, 38 and magnetized by contact with the electromagnet 36. The chain is attracted to the grapple 95 and pushed under the ship 103 by manipulating the chamber. The grapple is then de-magnetized and drawn back, leaving the chain beneath the ship. The chamber is then movec. to the other side of the ship, and the grapple mag. netized and pushed beneath the keel to pick up the end of the chain, which is then drawn through and lifted to the surface.
